The list grows we are 600+ strong that is over a 100 new members in the last month and a half. Not much activity on the list from message posting lately mabye...
My EDM stuff is paused, I have worked out a servo system for smooth wire supply and tensioning and then had to spend a lot of time sorting out my workshop,...
My electronics box is complete and quite a number of the mechanical parts are good to go. I had hoped to spend a goodly amount of time working on the project...
I'm still gathering parts. Takes a while on government retirement pension. Couldn't get the high power resistors locally, so got to it another way...I...
I just joined and have been reading past posts. I've yet to get the book but I'm pretty interested in building...will be strongly interested in the pulse...
My construction is paused. Just started a new job that's taking a lot of extra time. I have all the electronics and some of the mechanicals. Hope to build...
... The tricky bit is preventing rotation of the actual quill I've seen some nice ones with a small ball race attached to the inner tube running in a slot in...
Light bulbs can be used but are not necessarily the best choice. As they heat up the resistance increases which means that the charge time on the caps goes up,...

Ben and all, When I got the first prototype printed circuit board, I had spec'd the wrong size holes for the capacitors. I also didn't really like the layout....
I finished the generator - we'll have to see if the power resistors hold out. I used very large aluminum resistors in parallel. I also substituted several...
From: "Derek Brodeur" <d-brodeur1@...> ... Some of the commercial EDM's have a pump that is also overkill. They have a T that feeds one end to a valve and...
From: "Ben" <bnf@...> ... I'm waiting for the new book. Although it sounds like a fun project, to get much use from an edm, I would need to be able to get...
I always wonder why folks say "I will post photos if anyone is interested". Of course we are interested!!! Go ahead and post away I say! Errol Groff ...
Yes I have, it burns very quickly and leave kind of a slimmie swarf. I have a project right now burning 13MM blind Hexes 1/4" deep in a 1' diameter pieces for...
I read a while back that it was possible to burn alnico (aluminum/nickel/cobalt) magnets as they are a conductive metal. I know it wouldn't work with ceramic...
I don't have a clue as I have never attempted such a task. I think the swarf would be the lest of your problems. Let us know how it comes out. Ben ... From:...

g'day The swarf itself will be completely de-magnetized due to the high (melt) temperature. HOWEVER, it would likely be RE-magnetized by the magnet, although...
From: Derek Brodeur ... We needed a bunch of custom shaped ones for a job a while back and wire edm'ed them. The company we got them from said they strongly...
Thanks for all the information guys. I'll give it a whirl once I've got it all plumbed up. Good info! ... recommended we ... magnetized. ... and that...
Hi, I'd like to buy Ben Fleming's book. I sent him an email but never got a reply. Can anyone recommend a supplier (in Europe would be best)? I already...
try Lindsay Publications Inc. P.O.Box 538 Bradley Ill. 60915. That's where I purchased my book. Price is USD $ 19.95 Phone # is 815-935 5353 or Lindsaybks.com...
Hi, Thanks for the info. There's a redirect on Lindsay's website to : http://www.camdenmin.co.uk for european purchasers. So I just ordered the book from here...
ZP I am not sure why I never received your email perhaps it did not get through the spam filter. If you are still in need of a book let me know. I tried to...
Rob, I spent ~10.00 dollars and have a very nice working unit. It's a junk box project or you can buy every screw, resistor and chip. There are many ways to...
